Referring to the drawings :1 designates the front and back frames of a clock mechanism, which are arranged, in a suitable or desired manner, in opposed relation and spaced apart by suitable means such as spacing posts 2, to provide for properly locating the clock mechanism therewith.

3 designates the main or other spring of a clock, which, as here shown, is removably' connected at one end to the frame 1, as by a sleeve 7 mounted on a pin 5, carried on said frame 1, whereby it will be understood that when the main spring and coacting parts are released from the frame, the parts can be swung out and the sleeve 4 removed from the pin 5 and so the spring may be entirely removed. In order that the spring 3 may be released and removed from the frame 1 and connected therewith, without taking said frames apart or dismantling the clock mechanism, I provide a construction comprising a main drive gear or spur wheel 6, freely carried by a sleeve 7, a main gear 6, carrying a pawl 8 coacting with the ratchet 9, which is fixedly carried by the sleeve 7, and with which pawl 8 the spring 10 engages, which latter is carried by the main gear 6, and these parts serving the usual purpose and function.

The spring 3 is adapted to be connected with the sleeve 7 in any suitable manner, and, in the present instance, the said sleeve is provided with a struck up lug or projection 11, which is adapted tocooperate with the walls of an opening or slot 12, suitably formed adjacent the inner end of the main spring, whereby proper cooperation between the sleeve and the main spring takes place.

In order to removably connect the sleeve 1 and coacting parts, with the front and back frames 1, I provide an arbor 13 which is adapted to pass through suitable openings in the frames 1 and also through the sleeve 7,

and I provide means for removably connecting the said arbor with the main gear (5, here shown as through the medium of the sleeve 7, and I provide means for removably connecting the arbor with the frame.

Any suitable means may be employed for operatively and removably connecting the arbor with the sleeve 7.

In Figs. 1, 2, and 3, I have shown the arbor 13 as provided with the pins or projections 14., which are adapted to enter slots 15 formed in the sleeve 7. In Fig. 5, I have shown a set screw 16, for accomplishing this, said set screw being carried by the sleeve 7, and being adapted to engage the arbor 13 when properly actuated, and said arbor may be formed with a recess 17 for receiving the said set screw 16, if desired.

Any suitable means may be employed for locking the arbor to the frame 1, and I have shown in Figs. 1 and 2, a spring 18, which is carried by or mounted on the frame 1, and is so positioned as to enter the circular recess 19, formed in the arbor 13, and to seat therein to engage the walls of said recess 19, whereby the arbor 13 is permitted rotary movement, but is held laterally so that it is locked with respect to the frame 1. I preferably mount a boss 20 on the frame 1, having bore which is in line with the opening in the frame 1, so that the end of the arbor 13 will enter the boss 20, and I provide a slot 21 in the boss, communicating with the bore thereof, and so positioned that when the end of the arbor 13 is seated in the boss, the circular recess 19 is in register with the slot 21 of the boss, and as a suitable part of the spring 18 is positioned to move in said slot 21, it will always be properly guided to seat in the said circular recess 19 of the arbor 13. I preferably desire to bevel the end of the arbor 13, as at 22, so that it will be understood that in order to lock the arbor in position, it is only necessary to insert the same through the openings in the frame 1 and through the sleeve 7, and, as the end of the arbor passes into the boss 20, the beveled end of the same will force out the spring 18, allowing the head of said boss to pass said spring until the circular recess 19 comes into alinement with the spring 18, which enters and engages the same, and the arbor is locked in position. In order to remove the arbor, the said spring is removed, manually from the said circular recess 19, and immediately upon which the said arbor may be withdrawn, it being understood, when the arbor is of the form shown in Figs. 1, 2 and 3, that when the same is inserted in the frame, the pins 14. will enter the slots 15 in the sleeve 7, so that said arbor and sleeve will be suitably connected.

Then the construction shown in Fig. 5 is employed, it will be seen that when the arbor is inserted, as previously described, the reeess 17 in the arbor will be brought into proper position with the set screw 16, which latter may then be actuated to enter the said recess, and the arbor will be locked with respect to the sleeve or main gear, as previously described.

I may, if desired, employ a set screw in place of the spring 18, and in Fig. 1-, I have shown a construction wherein I have provided the boss 20 with a suitable threaded opening to receive a set screw 23, it being understood that after the arbor 13 is inserted in place, the circular recess is located in alinement with the said set screw 23, which can then be manipulated to enter the circular recess 1S), and so engage the walls thereof to lock the said arbor with respect to the frame 1, as previously described.

In Figs. 8, 9, 10 and 1.1, I have shown a construction wherein I provide means for removably connecting a suitable portion of the main spring with the frame, in order that when the arbor is removed, the said main spring and main gear, with which the said main spring is removably connected, are entirely free from the frame and can be immediately removed therefrom. In this coi'istruction, I have shown parts similar to that already shown and described, and have connected a suitable portion of the main spring 3 with the sleeve 7, as heretofore, and I will now describe the novel means for connecting a suitable portion, that is, for example, the other end of the said spring 3 with the frame 1. In this form, I provide a barrel 24, which is suitably formed in order to entirely receive the spring through an open side of said barrel, and I secure the free end, in any suitable manner, to said barrel. As here shown, I have provided a pin 25 for this purpose. The barrel is provided with a suitable opening, in which is situated the sleeve 7, so that said barrel 24 will thus be carried by said sleeve.

26 designates a lug suitably supported on the barrel Q l, which is spaced therefrom, in order that a suitable portion of the frame 1 can be situated bet-ween the said lug 26 and the face of the barrel 24, said lug being provided with the slot 27, forming a yoke, which is adapted to be situated in line with the opening in the frame, through which the arbor 13 passes in order that said arbor will be seated in said recess and will thus prevent rotation of said barrel 24, and by which means the said barrel will be removably connected with the frame, and as the spring is connected with the barrel, it Will also be removably connected as well, it being understood that the said barrel 24 is thus provided with means, which coact with the arbor for removably connecting the said main spring with the frame 1.

It will be further understood that by means of this construction, the arbor 13 serves as the sole means for connecting the parts with respect to the frame 1, that is to say, when the arbor is inserted in the frame and sleeve 7 and is seated in the recess 27, the parts are locked to the frame 1, but when the arbor 13 is removed, it entirely releases all of the parts coacting, that is to say, the main spring, the main gear, the sleeve 7, and the spring 3, which parts can be entirely removed at once, without further manipulation, from the frame 1.

It will now be apparent that I have devised a complete, unitary structure, simple in construction, eflicient in operation, and wherein the parts may be readily disassembled to renew or repair parts thereof, without disturbing other parts thereof.

Other modes of applying the rinciples of my invention may be employed 'or the mode herein explained. Changes may be therefore made, as regards the mechanism thus disclosed, provided the principles of construction set forth respectively in the following claims are employed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a clock, a main spring, a sleeve in suitable connection with said spring, an arbor, means on said arbor for engagement with said sleeve, a frame on which said arbor is mounted, said arbor having a continuous circumferential groove therein, and a device for laterally controlling said arbor in its bearings on said frame, the same being connected movably with said frame and adapted freely to occupy said groove, whereby said arbor may be rotated to cause said means to engage with said sleeve.
